| Abstract: | It has been observed that, when a Fabry-Perot interferometer was illuminated through a diffuser with light from a Q-switched ruby laser, the speckle smeared out in the Fabry-Perot rings. This is interpreted as a movement of the individual speckle resulting from the frequency chirping of light from the ruby laser and the high resolution of the Fabry-Perot interferometer. |
